LUBRICATOR FOR SPINNING MACHINERY.

Specification of Letters Patent No. 31,972, dated April 9, 1861.

To all lwhom 'it may concern:

Be it known that I, CHARLES HARDY, of Biddeford, in the county of Yorkand State of Maine, have invented an Improvement4 in LubricatingApparatus; and I do hereby declare that the following is a full' andeXact description thereof, reference being had to the accompanyingdrawings, and to the letters marked thereon. p

Figure I is a perspective view of the rings the spindles and rail of aring spinningframe, and position of the oil can and its attachments foroiling the rings. Fig. II is a front view of the fliersthe spindles andrail of a throstle spinning frame with outline of the can for oiling thespindles; Fig. III view of the can for oiling the rings; Fig. IV view ofcan for oiling the tips of the iiiers; Fig. V, view of can for oilingthe spindles; Fig. VI, vertical section on the line S, T, Fig. III.

It is well known that the present modes of applying oil to machinery forlubricating purposes are in many cases `very imperfect, involving greatwaste of the oil by its application in larger 4quantity than isnecessary and upon parts that do not require it; for instance, thespindles of a throstle spinning frame are usually oiled after eachdofting by applying one or more drops of oil from the nose of an oilcan, which mustbe moved from one spindle to another, thus requiring muchtime and wasting the oil as the can passes the spaces between thespindles where no oil is required. A drop of oil is usually applied tothe tip of each spindle while only a very small fraction of a drop isactually needed. The oil thus applied in excess is thrown off bycentrifugal force, a small portion only remaining upon the parts thatrequire lubrication.

From the trials made with my improved oiling apparatus I find that morethan half of the oil usually required in a spinning room can be saved,the best results being attained in those machines that have a largenumber of. bearings, which require oiling often, and occupy a fixedposition with reference to certain parts of the machine which serve asguides to the cans or feeders.

I will first describe the mode of oiling the rings of a ring spinningframe.

The frame of the machine is seen at A, Fig. I. The whirl B receives theband which drives the spindle C. This `is central with the rings E Ewhich rest upon the ring rail D.

In order that the travelers H H may move freely it is necessary that oilbe applied to the rings. This is eifected by means of the can and itsattachments as represented in Fig. III. The can I, is made of anyconvenient size, and the oil is introduced at the hole J, in which ascrew cap is fitted. On the opposite side of the can there is a smallaperture P, through which oil will escape when the can is inverted. Uponeach side of this opening there is a small stud or pin N N which holds anarrow loop of woolen cloth M- the lower side of the cloth bei'ngincontact with the opening. I/Vhen the can is inverted the oil escapes andsaturates the woolen cloth. Upon the top of the can there is a squareprojection Q, the top of which K is at any required height above the topof the cloth M, and at right angles with it there is a thin, projectinglip L.

The can, Fig. III is designed for oiling the top of the rings E E, Fig.I, being placed for this purpose in an inverted position. In thisinstance the height ofthe part Q K is such that when the face Ktraverses upon the ring-rail D, the woolen cloth may just touch the topof the ring. The

thickness of the part K is nearlyequal to the space between the face ofthe rail D and .the ring, while the ledge L defines the posi`V` tion ofthe can in a horizontal position'.

To oil the rings, the can is inverted and the parts K L applied to thecorner of the ring-rail. It is then pushed, rapidly, from one end of thespinning-frame to the other, a distance of about sixteen feet andapplies the oil to sixty or seventy rings in three or four seconds. Thewoolen cloth being slightly elastic, the oil is applied at F upon theinner edge of each ring and at G upon the outer edge, a small quantityof oil beingthus uniformly distributed at the precise point where it iswanted.

Fig. II represents a part of a throstle spinning frame. The spindle isshown at d, central with the fliers e, which are driven by the whirlf:-the parts requiring oil are the tip of the flier-nose g, and thelower part of the spindle d, the can shown in Fig. V being adapted forthis purpose.

The can for oiling the tip g, of the iiiers is shown in Fig. IV; is thecan, n saturated cloth over the hole o, c k gage, attached to the top ofthe can by means of the slot and screws p mf-p m Which aiord means ofadjusting the gage or lip la in any required position. When the can isinverted and the ledge or lip 7c slides upon the top-plate b, oil isapplied to the tip of the nose g.

In the above description of my system of lubrication I have referred toits use upon spinning machinery only, but it is obvious that the samemay be applied to all kinds of machinery Where oil is required.

What I claim and desire to secure by Letters Patent is- The oil-can orfeeder having upon its eX- terior, projecting guides or gages, so placed15 with reference to the saturated cloth or' may come in contact withthose parts of 2o the machine that require to be lubricated. CHARLESHARDY. [n s.]
